A slide positioner for moving a structural member (9) from an inoperation position to a working or operating position has a square sliding shaft (10) supporting sai d structural member (9). Two bearing assemblies (11, 12) are adapted for supporting said sliding shaft (10) and are spaced one from the other and being connected to a stationary base (20). One (11 ) of the bearing assemblies is rigidly connected to a pneumatic cylinder (29) whose piston rod (30) is connected to the sliding shaft (10). The bearing assemblies (11, 12) being mountable to the base (20) in various angular positions (a - f) after having been pivoted around an axis which is parallel to the axis of the sliding shaft (10) (Fig.1). |
